| Summary | 0003129: ACMI speedup by ordering in boundary | ||||
| Description | If there is a large difference in the ACMI sizes having the boundaries with the smallest faces first in the boundary file will have a drastic effect on speedup. ACMI2_couple { type cyclicACMI; nFaces 16176; } ACMI3_couple { type cyclicACMI; nFaces 16176; } ACMI1_couple { type cyclicACMI; nFaces 1080; } ACMI4_couple { type cyclicACMI; nFaces 1080; } Will use ~1min to do the addressing ACMI1_couple { type cyclicACMI; nFaces 1080; } ACMI4_couple { type cyclicACMI; nFaces 1080; } ACMI2_couple { type cyclicACMI; nFaces 16176; } ACMI3_couple { type cyclicACMI; nFaces 16176; } Will use 5s! to do the addressing | ||||
| Additional Information | Having a check for smallest of the patches first and do the addressing that way will have a huge performance saving when doing the mapping each iteration for transient runs. | ||||

Thanks for the information. We need maintenance funding to deal with the growing number of open issues relating to AMI and ACMI: https://openfoam.org/news/funding-2019/ |
